Specification of Letters Patent.

Patented Aug. 21, 1917.

To all whom it may concern: I

Be it known that I, HARRY T. ANDERSON, a citizen of the United States, and resident of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Side-Dump Cars; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates-to side dump steel cars, and more particularly to a type of cars having inclined hopper sheets leading from the center of the car toward the sides, to the support of the car body in this type of car, and to the mounting and operation of the car door mechanism for the door as located at the side of the car. One desirable form of this car has doors of practically equal along thesides and past the point where the car body is mounted on the bolsters, and part of my invention relates to the construction of the car body to carry the load with cars having such doors. The invention also comprises different improvements relating more particularly to this class of car as hereafter described and claimed.

In the accompanying drawings Figure 1 is a side view of the car. Fig. 2 is a longitudinal central section showing the mounting. of the sheaves which are illustrated in full lines. Fig. 3 is a top or plan View of a car. Fig. 4 is a plan view with the bottom hopper plates removed to illustrate parts thereunder. Fig. 5 is a cross section on the line 5-5 Fig. 1. Fig. 6 is a cross section on the line 6-6 Fig. 2 showing the car door operating mechanism in position. Fig. 7 is a like view with the car door operating mechanism removed; and l ig. 8 is a detail perspective illustrating the construction of the hood and connecting parts.

The car is provided with suitable center sills which are illustrated as channel center sills at 2 extending through the length of the car and around which is built the bolster which is formed of a center diaphragm 3 and side diaphragms 4 with the bottom strap member 5 extending across below the center sills and connected to the diaphragms 4; the center plates 6 being located under the bolster. The car has the end SlllS 7 connected to the body portion and the vertical end wall 8 extending up to the top of the car. Suitable transoms 9 are also secured to the center sill and extend out toward the car sides. The car sides 10 are of plate girder type having the top angle chords 11, and the bottom chords 12 which, as illustrated in the cross sectional views, are of. obtuse Z-bar form being so constructed for the purpose hereafter described. The vertical members 10' by which said car side are formed into plate girders are located within the car body, as hereafter described, so that the outer car sides are flush, thus increasing the capacity of the car. The car is provided with the end inclined hopper portions 13 which extend from the end walls at a downward incline and are riveted to the inclined bottom sheets. These inclined bottom sheets 15 extend from the mid portion of the car body on a suitable incline and are connected at the top by the apex member 16 formed of an angle bar extending over and riveted to the top edges of the hopper sheets 15 and the hopper sheets are supported by both the bolster and end car construction and the cross hood construction, as hereafter referred to.

As shown particularly in Figs. 1 and 2 the doors near the end 'of the car extend from the end car construction past the bolster to the next cross hood and this requires a peculiar construction and system of support between the center sill and car sides, the end portions of the car sides being supported by the endsill construction, the car sides being connected to said end portions and the next point of support for the car sides being found in the hood construction beyond the bolster. In the mid portion of the car the doors are located between and joining the hood portions and the sheaves of the car door operating mechanism are located within such hoods and under the inclined end hopper portion 13, the load on sides of cars being thus primarily sustained by the side and transmitted from the end sill construction and the next adjacent cross hood construction of the center sill and thence back to the bolster. The other cross hood constructions also serve to give support to the car sides and carry it to the center sills through which the load is carried to the bolster below the car sides with space be- 105 tween the car sides exposed at the sides of the car, thus giving access to the car door mechanism as shown in .Fig. 1 and also illustrated in the other sectional views.

As shown in Fig. 6 support is given to the 110 25 the same downward 1ncl1ne as the upper for the door.

inclined hopper sheets at the bolster by means of the triangular diaphragm plate 17 which extends across above the center sill cover plate 18 and has the flange 19 riveted to the upper flanges of the bolster" diaphragms 4 and the top flanges of the centersill and have also the flanges 20 extending under and riveted to the inclined hopper sheets'15, full support being thus given to the inclined hopper plates above the bolsters.

The bolster diaphragms 4 have flanges only on three sides, the outer edges of such bolster diaphra-gms being inclined corresponding to the incline of the hopper plates I and being connected thereto by angles 21 which are also secured to the hopper plates and which extend down to the lower edge of the door opening, being riveted to the 1ongitudinally extending car members 22.

These car members are formed of oflset bars to stiffen them, that is, the body of the bar is riveted to the angle 21 of bolster con- 'struction and to the hopper plate at its lower edge and the bar is then off-set downwardly as at 23 and then extends at about portion of the bar to form the discharge lip 24 of the hopper, the off-set 23 in addition to stiffening the bar acting as a stop shoulder over the hood plates 29 as well illustrated in Fig' 8. The inclined hopper plates 15 extend between the cross hoods and between the outer cross hood and the end of the car, and the cross hoods having flanges. 30 fitted below the inclined plates and riveted there to. The inclined hopper plates also are supported from the transoms by means of the center pedestal 31 which rests upon and is riveted to the center sill cover plate 18 and extends up toward the apex of the inclined bottom and has flanges 32 riveted to the upper portions of the inclined hopper plates. The cross hoods 29 extend up for practically the full length of the inclined hopper lates,

their upper portions 33 being inwar ly inclined and the flange 30 being correspondingly bent as at 34 to fit the top portion of the inclined hopper plates. At the top edge of the roof portions 33 of the hoods are flanges 35 which are riveted to each other with vertical-cross plates 36 fitted in between and riveted to said flanges, said vertical This off-set bottom car memcross plates being braced at their top edges bythe cross angles 37 which extend entirely across the car body, said angles having flanged edge portions 38 riveted at the top and bottom of the angles to the cross plates and said cross angles thus'bracing the car extending over and being riveted to thecar sides 10. In this way the car sides are braced by the entire construction of the hood including the cross angles37. Flanged gusset plates 40 are carried from the angle bars 37 up to the top chords 11, such gusset plates being riveted to the flanges 38 of the cross angles and their inner edges being flanged at 41 and riveted to the car sides, thus continuing the vertical stifleners formed by the vertical hood members 29 up tothe tween the hood and end portion of the car as shown in Fig. 2, the intermediate stiffeners extending between the top and bottom chords 11 and 12 of the car sides.

It will thus be seen that the load is carried principally by the center sill which supports the car sides over the bolster between the ends of the car to the next adjacent cross hood, the car sides being securely connected to the hood members through the cross angles 37 and the cross plates 36 and the entire cross hood construction, the bolsters being thus bridged and the load transmitted to them not only through the center sills, but by the triangular diaphragm 17 directly above the bolsters and by the inclined hopper plates resting on and secured thereto.

.7 The car doors are formed of flanged plates 45 of proper size having the top flanges 46, the bottom flanges 47 and edge flanges 48. They are hinged to bracket castings 49 secured on the outside of the obtuse Z-bar bottom chords 12, the upper ends of the doors being located under said Z-bar chords, while their lower edges when closed contact with the off-set bars 22 secured at the base of the inclined hopper plates 1?), the off-sets 23 of said bars forming the abutments against which the doorsclose. Extending the full length of the car are the channel bars 50 by which the doors are opened and closed, said bars extending across the open ends of the hoods and the doors operating mechanism being connected to said channel bars in said space.

While any suitable character of door oper-. ating mechanism may be employed I prefer and have illustrated substantially the mechanism" of LettersP-atent No. 616,811, granted to Simonton, December 27, 1898, the same simultaneously. sheave is the chain 74 connected to the mamas being modified to suit the'conditious of use. For operating the doors I provide the main center operating shaft 53 mounted centrally of the car directly under the apex 16 and under the inclined hopper plates and under the hopper plates in the different crossmembers, for example extending through journal bearings secured to the end wall 8 of the car, the center diaphragm 17 above the bolsters and the pedestals 31, the shaft having ratchet and pawl mechanism 54 at the end of the car. This shaft carriesa series of chain sheaves 55, 56, at the ends of the car,

and 57 and 58 at each cross hood. As more clearly shown'in Fig. 5, mounted in suitable bearings on the transoms 27 at the hoods and like transoms 59and 60 at the ends of thecar are the, sheave levers 61 at the hoods and 62 at the end of the car, these sheave levers being substantially the same in construction as shown in said Simonton patent, having pivots 63 and straight bearing faces 64, links 65 being pivoted at 63, the operating bars 66 having hooks 67 at their upper ends leading from abutments 68 on the sheave levers, said hooked arms 66 extending out and being connected by clevices 70 to the longitudinally extending channel bars 50 connected to the doors. Each central chain sheave mounted on the shaft 53 is connected by chains to a sheave lever on-each side of the car. For example at the cross hood the sheave 58 as illustrated in Fig. 5

is connected by the chain 72 on one side of the sheave lever to the right of said lever, the chain being positively connected to both the central sheave and the sheave lever and acting on the turning of the central shaft to close the door by turning the sheave to the left in which case the link 65 fits against one side of the abutments 68. and as the sheave is turned further the hooked arm 67 fits over said abutmentland rests against the face 64 and the dolor is thus drawn close. For convenient illustration the doors are shown'as open on the right of Fig. 5 and closed on the left thereof, it of course being understood that the door operating mechanism does not in practice permit of this relative position but that the doors are so mounted that the turning of the main shaft operates to open the doors on each side of the car simultaneously and to close them Carried from the same sheave lever on the other side of the car so that when the sheave lever is turned in the proper direction for closing both doors will he closed at the same time. In like manner chains 7 3 and 75 are connected to the sheave 57 on the central shaft and extendto the two sheave levers so that by the turning of the central shaft in the opposite direction the sheave levers are turned back by the pull of those chains to cause the opening of t e doors, as shown to the right of Fig. 5. In the use of this type of door operating apparatus in side door cars such as those illustrated, it is important that means be provided to-hold the doors open and at the same time to stop the movement of the parts when the doors have reached their farthest outward swing. To that end the links 65 are provided with shoulder lugs 76 which, when the door is forced out to the full extent ,desired, contact with the hooked ends'67 of the arms 66 and by contact therewith prevent further turning of the main operating shaft by stopping the further movement of the sheave levers and holding the doors in outward position until the shafts are turned in the opposite direction to close the doors as herein described.

It will be noticed that to give the above operation, the chains on one side of the car such as those leading from the chain shaft 58 are crossed. This is necessary to cause the simultaneous opening and closing of the doors through the turning of the sheave levers as above described, and to get the necessary movement while turning the main shaft and its chain shafts in the same direction.

Practical use has shown that the above car door operating mechanism is very efiicient in providing for the simultaneous opening and closing of the doors throughout the length of the car and accomplishing this without any great strain upon the operating shaft or the other operating parts as the connection with the chain on both sides of the sheave levers and operating in both directions therefrom provides for distributing this strain throughout the entire length of the car and the simultaneous drawing of all doors to closed or opened position.
